+// This file ensures that canceling a channel early does not
+// send the request to the server (bug 350790)

+// I've also shoehorned in a test that ENSURE_CALLED_BEFORE_CONNECT works as
+// expected: see comments that start with ENSURE_CALLED_BEFORE_CONNECT:
+//
+// This test also checks that cancelling a channel before asyncOpen, after
+// onStopRequest, or during onDataAvailable works as expected.
